The water received by the water receiving structure flows back along the side wall of the water receiving structure and is converged with the water in the atomizing chamber 7.

In this embodiment, as shown in fig. 2 to 4, the water receiving structure preferably includes: a cover opening 120 formed in a top wall of the first cover body portion 110, the top wall being a wall surface of the first cover body portion 110 away from the atomizing chamber 7; a tubular part 121 connected to the cover opening 120 and extending into the atomizing chamber 7, and having a first through hole 112 for allowing an atomizing airflow (the atomizing airflow is an airflow formed by mixing an airflow entering the atomizing chamber 7 and cold mist generated in the atomizing chamber 7) to enter the tube inner space; and an end portion 122 disposed at an end of the tubular portion 121 far from the cover opening 120, and having a second through hole 113 communicating the space inside the tube and the atomizing chamber 7. In the water receiving structure with such a structure, preferably, the cover opening 120 is a circular opening, and the tubular portion 121 connected to the lower side of the cover opening 120 is also preferably a circular tube structure, more preferably a tapered tube structure with a diameter gradually decreasing toward a direction away from the cover opening 120, and the end portion 122 (without considering the second through hole 113) is a plate-shaped portion for blocking a port of the tubular portion 121 away from the cover opening 120, so that the shape of the whole water receiving structure is an inverted frustum shape, thereby being more beneficial to the backflow of water. The first through hole 112 is formed in the tubular portion 121, so that the atomizing chamber 7 and the inner space of the tubular portion 121 can be communicated, and the air flow entering the atomizing chamber 7 can drive the cold mist to flow through the first through hole 112 and enter the inner space of the tube, and can flow out from the cover opening 120 communicated with the inner space of the tube (the atomized air flow after flowing out enters the mist discharge pipe 14 again), as shown by arrows in fig. 6, 9 and 10, so that the cold mist can be driven and discharged in an accelerated manner. Specifically, in order to make the airflow and the cold mist have a larger flow area, as shown in fig. 3 and 4, it is preferable that the first through holes 112 are strip-shaped holes opened in the circumferential side wall of the tubular portion 121, the strip-shaped holes extend from one end of the tubular portion 121 near the cover opening 120 to one end near the end portion 122, and a plurality of the first through holes 112 are provided at equal intervals in the circumferential direction of the circumferential side wall. Due to the arrangement of the first through hole 112, when the water receiving structure receives water splash, the water splash can pass through the first through hole 112 and enter the pipe inner space, so that water entering the pipe inner space can normally flow back, the end portion 122 is provided with the second through hole 113, the second through hole 113 can be a circular hole with a large area and arranged at the center of the end portion 122, and a plurality of strip-shaped holes with large opening areas and arranged around the central circular hole can be further included on the basis, as shown in fig. 3 and 4.

Specifically, as shown in fig. 2, 3, 4, 9 and 10, the first cover body portion 110 is provided with a first air inlet 114 communicating with the atomizing chamber 7 and the cover opening 120, and the air flow introduced by the air inlet member 10 can enter the atomizing chamber 7 from the first air inlet 114 and flow out from the cover opening 120.

The first cover body portion 110 is further provided with a first airflow outlet 115 communicated with the first airflow inlet 114 and the space above the first waterway 9, the first airflow inlet 114 enables airflow introduced by the air inlet member 10 to enter the upper portion of the first waterway 9, and airflow introduced by the air inlet member 10 can flow into the first cover body portion 110 from the first airflow inlet 114, pass through the upper portion of the first waterway 9 and then flow out through the first airflow outlet 115. When the atomizing chamber 7 is in communication with the space above the first flume 9, the first airflow outlet 115 also enables an atomizing airflow (which includes heat absorbed from the first flume 9) to flow over the atomizing chamber 7 and the first flume 9, and finally out of the first airflow outlet 115.

The second cover body portion 111 is provided with a second air inlet 116 which is in communication with the heating chamber 5 and allows the air flow introduced by the air inlet means 10 to enter the heating chamber 5, and a second air outlet 117 which is in communication with the heating chamber 5 and allows the heated air flow (the heated air flow refers to the air flow formed by mixing the air flow entering the heating chamber 5 and the steam generated in the heating chamber 5) to flow out of the heating chamber 5. Wherein, because the atomizing chamber 7 and the first water channel 9 are covered under the first cover body 110, when the first cover body 110 covers the atomizing chamber 7 and the first water channel 9, preferably, a gap is provided between the top wall of the first cover body 110 and the mounting surface 3, that is, a space covered by the first cover body 110 is provided above the opening of the atomizing chamber 7 and above the opening of the first water channel 9 (hereinafter, this space is referred to as a covered space), after the air flow enters the first cover body 110 from the first air inlet 114, the air flow first flows in the atomizing chamber 7 and a part of the covered space above the atomizing chamber 7, then a part of the air flow enters the first through hole 112 to carry out the cold mist in the atomizing chamber 7, and the other part of the air flow enters the part of the covered space above the first water channel 9 and the first water channel 9, because the first air outlet 115 is disposed at a position of the covered space above the first water channel 9, that the first air outlet 115 is disposed above the first water channel 9 and aligned with the first water channel 9, the heat of the air flow is taken out from the first water channel 9, and the air flow can be swept. That is, the airflow enters the atomizing chamber 7 and the first water channel 9 through the first airflow inlet 114 formed on the side wall of the first cover body 110, and when the airflow is required to flow out of the first cover body 110 to further flow to the outside of the humidifier after purging the atomizing chamber 7 and the first water channel 9, as can be seen from the foregoing, the cold mist generated in the atomizing chamber 7 flows through the first through hole 112 and flows out of the cover body opening 120 under the driving of the airflow, and in order to facilitate the outflow of the airflow carrying heat after purging the first water channel 9, the first airflow outlet 115 for leading out the airflow purging the first water channel 9 is preferably formed at the top of the first cover body 110, so that the cold mist and the heat can flow out of the first cover body 110 from different paths in a more targeted manner.

Of course, since the atomizing chamber 7 and the first water passage 9 inside the first cover body 110 communicate with each other through the cover space, the air flow entering the first cover body 110 from the first air inlet 114 may flow out of the cover opening 120 and may flow out of the first air outlet 115, so that the first air outlet 115 can simultaneously flow the atomized air flow out of the atomizing chamber 7 and the first water passage 9, and similarly, the cover opening 120 can simultaneously flow the atomized air flow out of the atomizing chamber 7 and the first water passage 9.

The second air inlet 116 and the second air outlet 117 provided on the second cover body 111 provide a flow path for the air flow to enter and exit the heating chamber 5, and the air flow enters the heating chamber 5 through the second air inlet 116 and then blows the steam, so that the steam rapidly flows out from the second air outlet 117, and thus the steam can be driven to be discharged through the air flow, and compared with the prior art that the steam naturally drifts away, the steam outflow speed can be significantly increased.

Further, as shown in fig. 6 and 7, a flow guiding member 12 is convexly disposed at the bottom of the water tank 1 for being engaged with the base 2, when the water tank 1 is engaged with the base 2, the flow guiding member 12 abuts against the base 2 and encloses with the base 2 to form an air inlet channel 13 for guiding air, one end of the air inlet channel 13 is communicated with the first air inlet 114, the other end of the air inlet channel is communicated with the heating chamber 5, and the air inlet member 10 at least partially extends into the air inlet channel 13; and: the first channel section 130 of the air intake channel 13 located between the air intake component 10 and the first air inlet 114, the first water channel 9 and the first air outlet 115 form a first air channel 01; the first channel section 130 of the air intake channel 13, which is located between the air intake component 10 and the first airflow inlet 114, the atomizing chamber 7, the first through hole 112, and the inner space of the tubular part 121 and the cover opening 120 form a second air duct 02; the second passage section 131 of the air intake passage 13 between the air intake part 10 and the second air intake 116, the heating chamber 5, and the second air outlet 117 constitute a third air passage (i.e., the portion of the air intake passage 13 between the air intake part 10 and the heating chamber 5, which constitutes a part of the third air passage). The structure is a specific structure forming the first air duct 01, the second air duct 02 and the third air duct 03, wherein, as shown in fig. 7, the guiding member 12 disposed at the bottom of the water tank 1 includes two parts, one part encloses an approximately rectangular annular structure, and the other part is a strip-shaped plate structure, the plate structure is located inside the annular structure and encloses the air inlet channel 13 with a side wall surface of the annular structure and the mounting surface 3, when the water tank 1 is placed on the base 2, the annular structure surrounds the covering member 11 and the air inlet member 10 when abutting against the mounting surface 3, so that the air supplied from the air inlet member 10 can only flow to the covering member 11 and not flow to other parts of the mounting surface 3 by the blocking of the annular structure, and the plate structure disposed inside the annular structure is located between the air inlet member 10 and the covering member 11 when abutting against the mounting surface 3, so that the air inlet member 10 is located in the air inlet channel 13, since the air inlet member 10 has two air outlets (similar to have two outlets) facing the first air inlet port 114 and the second air inlet port 116, the air inlet channel 13 is located at opposite positions of the air inlet channel 13, and the air inlet channel 13 is located at opposite directions 130. As shown in fig. 8 and 9, the first air inlet 114 disposed on the first cover portion 110 is communicated with the air inlet channel 13 at one end of the air inlet channel 13 (the section therebetween is the first channel section 130), and the second air inlet 116 disposed on the second cover portion 111 is communicated with the air inlet channel 13 at the other end of the air inlet channel 13 (the section therebetween is the second channel section 131), so that the first air duct 01 is formed by the cooperation of the air inlet channel 13, the first cover portion 110 and the first water channel 9, that is, as shown by the thick solid arrows and the arrows formed by small dots in fig. 6, 9 and 10, the flow guide path of the first air duct 01 is the first channel section 130 of the air inlet channel 13, the first air inlet 114, the flow guide space of the first water channel 9, the cover space above the first air inlet and the first air outlet 115; a second air duct 02 is formed by the cooperation of the air inlet channel 13, the first cover body portion 110 and the atomizing cavity 7, that is, as shown by thick solid line arrows and thin solid line arrows in fig. 6, 9 and 10, a flow guide path of the second air duct 02 is a first channel section 130 of the air inlet channel 13, a first airflow inlet 114, the atomizing cavity 7, a first through hole 112 arranged on the water receiving structure, an inner space of the tubular portion 121 and the cover body opening 120; the third air duct 03 is formed by the cooperation of the air supply passage 13 and the second hood portion 111, that is, as shown by dotted arrows in fig. 6, 9 and 10, the guide path of the third air duct 03 is the second passage section 131 of the air supply passage 13, the second air inlet 116, the heating chamber 5 and the second air outlet 117. As can be seen from the above, the first air duct 01 and the second air duct 02 have overlapped portions, that is, the first channel section 130 of the air inlet channel 13 and the first air inlet 114, that is, the first air duct 01 and the second air duct 02 share the path of the overlapped portions, and the air flow is divided after entering the covering space.

Based on the above structure, when the humidifier needs to discharge cold mist, the air inlet part 10 is made to discharge air, and the air flow sequentially passes through the first channel section 130 of the air inlet channel 13, the first air flow inlet 114, the atomizing chamber 7, the first through hole 112 arranged on the water receiving structure, the tube space and the cover opening 120, in this process, the air flow sweeps the cold mist generated in the atomizing chamber 7 to drive the cold mist to enter the mist discharge tube 14 after passing through the water receiving structure, so as to achieve discharge to the outside of the humidifier, meanwhile, in this process, the air flow can only flow along the first air duct 01 and only drive the cold mist to discharge under the control of the air inlet part 10 (for example, the air outlet facing the second channel section 131 is closed), or the air outlets on both sides of the air inlet part 10 can be made to discharge air, that is also to flow through the third air duct 03, but at this time, the heating part 6 does not heat water, that is the heating part does not generate steam, so the purpose of only discharging cold mist can be achieved; when the humidifier needs to discharge hot mist, the air outlets on both sides of the air inlet component 10 are all used for exhausting air, a part of air flow generally flows through the first air duct 01 so as to enable cold mist to enter the mist discharge pipe 14, while the other part of air flow sequentially flows through the second duct section 131 of the air inlet channel 13, the second air flow inlet 116, the heating cavity 5 and the second air flow outlet 117, in the process, the air flow sweeps steam (heating air flow) generated in the heating cavity 5 so as to drive the steam to enter the mist discharge pipe 14, and meanwhile, the steam and the cold mist entering the mist discharge pipe 14 are mixed in the mist discharge pipe 14 so as to generate hot mist with moderate temperature.

In the present embodiment, it is also preferable that, of the two air outlets of the air intake component 10, the opening area of the air outlet facing the first air inlet 114 is larger, and the opening area of the other air outlet facing the second air inlet 116 is smaller, so that the air flow to the atomizing chamber 7 is greater than the air flow to the heating chamber 5, so that the cold mist and the heat can be discharged more sufficiently, and the atomizing chamber 7 can also be the main atomizing chamber of the humidifier.

In the present application, as shown in fig. 7 and 8, the water tank 1 is provided with a mist discharge pipe 14 for discharging mist to the outside of the humidifier, the mist outlet is an outlet of the mist discharge pipe 14, the first air flow outlet 115 is a plurality of air outlet holes provided in the first cover portion 110 and disposed close to an inlet of the mist discharge pipe 14, and the second air flow outlet 117 is connected to a mist guide pipe 118 extending into the mist discharge pipe 14. The fog exhaust pipe 14 is the part that realizes that fog is discharged to humidifier outside and steam and cold fog mix, and make first airflow outlet 115 and fog exhaust pipe 14 be close to the setting (preferably set up well), then be favorable to the heat to the outside discharge of humidifier more, make the hydroenergy of first water course 9 can obtain timely cooling, and in this application in order to make the heat more timely, abundant discharge, improve thermal discharge efficiency, as shown in fig. 2, fig. 4 and fig. 9, it includes a plurality of ventholes that run through first cover somatic part 110 roof to prefer second airflow outlet 117, and these ventholes are the great bar hole of open area. In addition, since the atomization chamber 7 and the first water passage 9, which are simultaneously covered by the first cover body portion 110, communicate with each other inside the first cover body portion 110, the first air outlet 115 for discharging heat may not be provided exclusively, and the heat may be discharged through the first through hole 112 of the water receiving structure, the tube space, and the cover body opening 120 by the air flow. The protruding setting of second cover body portion 111 leads the fog pipe 118 with second air outlet 117 intercommunication to make during the fog pipe 118 stretches into the fog discharging pipe 14, not only can be more abundant with steam leading-in to the fog discharging pipe 14 in, but also can avoid heat loss, make the working effect of humidifier obtain promoting. Specifically, the overall length of the mist guiding pipe 118 and the length of the mist guiding pipe extending into the mist discharging pipe 14 may be adjusted according to actual working requirements, which is not limited in the present application.

More preferably, as shown in fig. 4, a wind shielding member 18 is provided on the inner wall of the second housing portion 111, and the wind shielding member 18 is provided adjacent to the second air inlet 116, preferably aligned with the second air inlet 116, and changes the flow direction of the air flow in the heating chamber 5 by blocking the air flow entering from the second air inlet 116. The wind shielding member 18 is a plate-shaped member, and is disposed on the inner wall of the second cover portion 111 and aligned with the second air inlet 116, so that it can block the air flow entering from the second air inlet 116, and disturb the air flow to change the flow direction of the air flow, so that the air flow can flow in multiple directions in the heating chamber 5 without order to more sufficiently purge the hot water liquid level and the internal space of the heating chamber 5, thereby promoting the flow of the steam to the second air outlet 117 and preventing the steam from flowing back out of the heating chamber 5 from the second air inlet 116.

As shown in fig. 1-4, 8 and 10, the water tank 4 and the atomizing chamber 7 are communicated through the second water channel 15, the covering portion (specifically, the top wall of the covering member) of the first cover body portion 110 is connected with a separation side wall 119 extending into the second water channel 15, and an edge of the separation side wall 119, which is far away from the top wall, can extend into the second water channel 15 below the water surface to block a portion of the second water channel 15 above the water surface, so that the cold mist can be prevented from being diffused into the water tank 4 from the atomizing chamber 7. Since the water tank 4 is adjacent to the atomizing chamber 7, closely disposed, and communicated through the second water passage 15, there is a case where the cold mist generated in the atomizing chamber 7 is diffused into the water tank 4 through the second water passage 15, which may cause waste of the cold mist. Therefore, in order to avoid this, it is preferable that the bottom of the top wall of the first cover body 110 is provided with a downwardly extending separation side wall 119, and when the first cover body 110 covers the atomizing chamber 7 and the first waterway 9, the separation side wall 119 extends into the second waterway 15, and since water is retained in the second waterway 15 and the cold mist is diffused above the water surface, when the second waterway 15 is blocked by using the separation side wall 119, it is only necessary that the separation side wall 119 extends from the mounting surface 3 to below the water surface, and it is not necessary to extend to the bottom wall of the second waterway 15.

As can be seen from the above, the cover 11 in the present application is a comprehensive component that can perform various functions such as noise reduction, heat transfer prevention, and formation of an air duct, and by providing this component in the humidifier, performance of the humidifier in various aspects can be improved, and the use effect of the humidifier can be significantly improved. Preferably, the covering member 11 is of an integral structure, and the material is preferably soft plastic, or may be hard plastic or the like.

It is further preferred that, as shown in fig. 8 and 11, a hot water cover 16 is provided in the heating chamber 5 and opens toward the bottom of the heating chamber 5, and the hot water cover 16 is located inside the second cover body portion 111. The hot water cover 16 is preferably a polygonal barrel-shaped cover surrounded by a plurality of side walls, for example, a quadrangular barrel-shaped cover shown in fig. 11, and is preferably made of plastic. The reason why the hot water cover 16 is additionally arranged in the heating cavity 5 is that the hot water cover 16 with the downward opening can cover the water in the heating cavity 5 at the inner side thereof, so that the noise is insulated in the process that the water is heated and boiled, and the double-layer plastic cover can be formed by the hot water cover 16 and the second cover body part 111, so that the noise generated in the water heating process can be isolated to a greater extent, and the silencing effect of the humidifier is better.

As shown in fig. 11, the hot water cover 16 includes: an inlet hole 160 provided in a portion of the hot water cover 16 close to an opening of the hot water cover 16 (hereinafter, this opening will be referred to as a hot water cover opening), and away from a communication port through which the first water passage 9 communicates with the heating chamber 5; and mist outlet holes 161 opened in the top wall of the hot water jacket 16 to allow steam to enter the heating chamber 5 from the jacket inner space of the hot water jacket 16. In this structure, since the opening of the hot water cover is located at the bottom of the heating chamber 5, the water inlet hole 160 is provided at a position of the hot water cover 16 close to the opening of the hot water cover, so that the water inlet hole 160 is also located at the middle lower portion of the heating chamber 5, and water can more conveniently enter the hot water cover 16. And, when seting up into the water hole 160 on the lateral wall of hot water cover 16, preferably make its intercommunication mouth of the intercommunication heating chamber 5 of keeping away from first water course 9, just so can increase the distance of water hole 160 and first water course 9, increase the degree of difficulty that the hot water in the hot water cover 16 flows into first water course 9 to can further make the temperature of water in the first water course 9 reduce, better avoid the rising of humidifier shell temperature. And set up the fog hole 161 on the roof of the hot water cover 16 close to the second cover body 111, can make the steam that the water produced when boiling pass the fog hole 161 and flow to the second air outlet 117, is favorable to the discharge of steam, this structure of the fog hole 161 can have multiple choices, as shown in fig. 10, it can be a bar hole that the open area that sets up on the roof is great, also can be a plurality of circular holes or square holes that the open area is smaller that evenly distributed on the roof, so that the roof becomes the grid structure.

In addition, the water inlet hole 160 is formed in the hot water cover 6, so that water in the first water channel 9 can flow into the hot water cover 6 through the water inlet hole 160 slowly, and the water inlet hole 160 can also play a role in reducing heat backflow because the flow rate of the water at the water inlet hole 160 is slow, so that the water temperature in the first water channel 9 cannot be too high. Of course, the primary means for reducing or even preventing heat transfer to the basin 4, housing in the present application is by flowing air through the first air channel above the first water channel 9 to dissipate heat from the water in the first water channel 9.

In order to increase the structural strength of the hot water cover 16, as shown in fig. 11, it is also preferable that a portion of the hot water cover 16 near the opening is provided with a flange 162 that protrudes from the side wall of the hot water cover 16 and extends in the circumferential direction of the hot water cover 16, and that acts like a reinforcing rib to prevent the hot water cover 16 from deforming in a high temperature environment.

For first waterway 9 disposed on mounting surface 3, it is preferred that at least portions of first waterway 9 be distributed in a central region of base 2, and portions of first waterway 9 be disposed away from a side wall of base 2. As shown in fig. 1, due to the limitation of the positions of the water tank 4, the heating cavity 5 and the atomizing cavity 7 on the mounting surface 3, the first water channel 9 cannot extend along a straight line, that is, the first water channel 9 is a bent water channel, and in order to avoid the temperature rise of the housing of the base 2 caused by the temperature rise in the first water channel 9, the distribution principle of the first water channel 9 on the mounting surface 3 is to be as far away from the side wall of the base 2 as possible, so as to reduce the heat transfer to the housing, but because the first water channel 9 is a bent water channel, in order to reduce the probability of the heat transfer to the housing to the maximum extent, a section of the first water channel 9, which is located between the heating cavity 5 and the atomizing cavity 7 and has a larger extension length, is distributed in the central area of the base 2, as shown in fig. 1.

As shown in fig. 1, first flume 9 includes: a first part 901 communicating with the water tank and located between the nebulizing chamber 7 and the housing of the base 2, and located closer to the nebulizing chamber 7 with respect to the housing; the second part 902 has one end communicating with the first part 901 and the other end communicating with the heating chamber 5, and is arranged at an angle with respect to the first part 901 to achieve the arrangement between the atomizing chamber 7 and the heating chamber 5, and is located in the central area. In this arrangement, the second part 902 of the first water channel 9 is located in the central region of the mounting surface 3, so that the second part 902 is located far from the surrounding casing of the base 2, and the first part 901 needs to be communicated with the water tank 4, and the water tank 4 is located close to the atomizing chamber 7, so that the first part 901 is inevitably required to be located between the atomizing chamber 7 and the casing of one side wall of the base 2, but in order to reduce the transfer of heat to the casing, when the first part 901 is located, the first part 901 is located parallel to the casing of one side wall of the base 2 and is located as far away from the casing as possible, that is, the first part 901 is located closer to the atomizing chamber 7. Through so setting up first water course 9, can make first water course 9 keep the biggest distance with the shell on the whole, reduce the heat as far as to the transmission of shell, furthest's promotion user's use experience.

In order to further reduce the heat transfer in the first channel 9, it is preferred in the present application, as shown in fig. 1, that a shut-off member 17 is also arranged in the first channel 9, which shut-off member 17 reduces the flow cross section of the first channel 9. The shut-off element 17 is preferably a plate-shaped element which is arranged on one side wall of the first waterway 9 perpendicular to the direction of extent of the first waterway 9 and has only a small gap with the other side wall of the first waterway 9, so that the hot water in the first waterway 9 is blocked and shut off, and the reverse flow and the reverse heat transfer of the hot water are prevented. More preferably, as shown in fig. 1, a plurality of closure members 17 are disposed on the entire first water channel 9, and the plurality of closure members 17 are distributed at different positions of the first water channel 9, so that multiple closure is realized at different positions of the first water channel 9, and the transfer of heat to the water tank 4 and the housing is reduced to the greatest extent.

In the present application, it is preferable that a fan for driving air to flow into the air inlet member 10 is provided in the base 2. That is, a fan for driving air to flow is provided in the base 2 to provide air flows to the second air passage, the first air passage, and the third air passage, so that cold mist, heat, and steam can be discharged more efficiently. In addition, the air flow can also be provided by an external component, for example, an air inlet pipeline communicated with the air inlet component 10 is arranged on the base 2, an air inlet interface is arranged on the outer shell of the base 2, and the air flow is provided for the second air channel, the first air channel and the third air channel by externally connecting an air source to the air inlet interface. Because the humidifier provided with the fan is more complete in structure and convenient to use, one or more fans are preferably added to the humidifier to provide air flow.

In the present specification, the structures of the respective portions are described in a progressive manner, and the structure of each portion is mainly described as a difference from the existing structure, and the overall structure of the humidifier can be obtained by arbitrarily combining the structures of the respective portions.
